/*
* Open Source RFID Access Controller - Ethernet Branch
*
* 3/21/2013 v0.05 (branch based on upstream 4/3/2011 v1.32)
* Will Bradley - will@heatsynclabs.org
* Short Tie - tie.short@gmail.com
*
* Upstream:
* Last build test with Arduino v00.21
* Arclight - arclight@23.org
* Danozano - danozano@gmail.com
*
* Notice: This is free software and is probably buggy. Use it at
* at your own peril. Use of this software may result in your
* doors being left open, your stuff going missing, or buggery by
* high seas pirates. No warranties are expressed on implied.
* You are warned.
*
* For latest downloads of this ETHERNET branch, check out
* https://github.com/zyphlar/Open_Access_Control_Ethernet
*
* For latest downloads of the UPSTREAM software, including
* Eagle CAD files for the hardware, check out
* http://code.google.com/p/open-access-control/downloads/list
*
*
* This program interfaces the Arduino to RFID, PIN pad and all
* other input devices using the Wiegand-26 Communications
* Protocol. It is recommended that the keypad inputs be
* opto-isolated in case a malicious user shorts out the
* input device.
* Outputs go to a Darlington relay driver array for door hardware/etc control.
* Analog inputs are used for alarm sensor monitoring. These should be
* isolated as well, since many sensors use +12V. Note that resistors of
* different values can be used on each zone to detect shorting of the sensor
* or wiring.
*
* Version 1.00+ of the hardware implements these features and uses the following pin
* assignments on a standard Arduino Duemilanova or Uno:
*
* Relay outpus on digital pins 6,7,8,9
* DS1307 Real Time Clock (I2C):A4 (SDA), A5 (SCL)
* Analog pins (for alarm):A0,A1,A2,A3
* Reader 1: pins 2,3
* Reader 2: pins 4,5
* Ethernet: pins 10,11,12,13 (Not connected to the board, reserved for the Ethernet shield)
*
* Quickstart tips:
* Set the privilege password(PRIVPASSWORD) value to a numeric DEC or HEX value.
* Define the static user list by swiping a tag and copying the value received into the #define values shown below under Adam, Bob, and Carl.
* Change MAC and IP as appropriate for your network.
* Compile and upload the code, then log in via HTTP to the IP you specified.
*
* Guide to log keys and data:
* A=alarm armed (# level)
* a=added user (# usernum)
* C=keypad command (# command)
* c=second half
* c=checked user (0=failed, #=found usernum)
* D=denied access (# card num)
* d=second half
* d=deleted user (# usernum)
* E=second (#=second)
* F=priv fail (0=wrong pw, 1=too many attempts, 2=not logged in)
* f=second half
* f=card fail (#=usermask)
* G=granted access (# card num)
* g=second half of card
* H=hour (#=hour)
* i=attempt to write to invalid eeprom address (# usernum)
* I=attempt to delete from invalid eeprom address (# usernum)
* L=locked (1=door1, 2=door2, 3=bedtime)
* M=minute (#=minute)
* m=alarm state (# level)
* R=read tag (# card num)
* r=second half of tag
* Q=superuser authed (#=superuser)
* S=auth (0=privileged mode enabled)
* s=alarm sensor (# zone)
* t=alarm trained (#=sensor value)
* T=alarm triggered (0)
* U=unlocked door (1=door1, 2=door2)
* Z=user db cleared (0)
* z=log cleared (0)
* Log Format:
* H M E
